Hepatitis A virus (HAV) infection usually has a self-limited clinical course and sometimes remains subclinical. HAV infection rarely causes neurologic problems. There are only a few case reports on seizure and meningoencephalitis associated with serologically confirmed hepatitis A infection. We report a case of a 27-year-old man admitted to the emergency department due to confusion after an episode of generalised tonic convulsion. Laboratory test results included AST 441 units/L and ALT 1294 units/L. A diagnosis of hepatitis A was confirmed by the finding of serum IgM-HAV antibody. HAV infection should be considered one of the aetiologies of meningoencephalitis.
